MACHINE FOR THE PRODUCTION OF TYPE-MATRICES OR SIMILAR BODIES.

Application filed January 15, 1913.

To all whom it may concern:

Be it known that I, FRANK HINMAN PIER- FONT, of Salfords, Horley, in thecounty of Surrey, England,.have invented a certain new and usefulImprovement in Machines for the Production of Type-Matrices or SimilarBodies; and I do hereby declare the following to be a full, clear, andexact description of the same, reference being had to the accompanyingdrawings, forming a part of this specification, and to the figures andletters of reference marked thereon.

This invention relates to apparatus or machines for measuring,justifying and milling type-matrices to accurate length and withaccurate depth of drive of the character or symbol. These matrices,which are generally rectangular in form, have a formative cavity with acharacter or other symbol impression punched or otherwise sunk in oneend. They are used chiefly in type casting and composing machines, and avery high degree of accuracy in their dimensions particularly as tolength and the depth of the matrix drive or cavity is required, themargin of error allowed being usually less than 2/10,000ths of an inch.These matrices have to pass through a number of processes and this,together with the great accuracy required renders their productioncostly to counteract which and to insure rapid and accurate productioncommercially, it is necessary that the machine employed should operateautomatically and without necessitating the attention of highly skilledoperators.

It is the chief object of the present invention to provide an automaticmachine in which the matrix will be milled to correct length and withcorrect depth of drive or matrix cavity so that the matrices leaving themachine will not only be of accurate and uniform length, within themargin of error allowed, but the depth of the drive will also be correctwithin the same margin.

According to the present invention, the matrices are automatically fed,singly, to an automatically operatedcarrier wherein each matrix beforereaching the cutters, is directly positioned by an automaticallyoperated needle engaging the character face in the matrix cavity.Further, the cutters or one of them are or is set relatively to theSpecification of Letters Patent.

matrix in accordance with a measurement obtained by an adjustablemeasuring device cooperating with the needle, and'previously set from astandard matrixor depth gage. hen the matrix has been positioned in thecarrier it is automatically locked against accidental displacement. Thecarrier, together with feeding and delivery galleys, is movablerelatively to the needle so as to bring in line therewith a requiredpart of the character or symbol, and this adjustment is performed inview of the operator through a microscope. Also as there is a limit tothe speed at which the actual cutting or milling can take placev andsuch speed, if constant during the entire cycle of the machine, wouldreduce the speed of operation considerably, an automatically operatingvariable speed gear is provided for the carrier.

The automatic matrix feeding and delivering mechanism which is providedaccording to thisinvention for loading and discharging the carrier, canbe rendered inoperative at will without interfering with the othermovements of the machine. Further, mechanism is provided for arrestingthe movements of the carrier at various points in the cycle.

The adjustable measuring device cooperating with the needle controls theclosing and breaking of an electric circuit so that when ever it touchesthe needle which is automatically advanced, it effects the closing ofthe electric circuit and is thereby automatically locked against furtheradvance. I

is a section showing the receiving galley and its pusher; and Fig. 15 isa section showing the method of delivering the matrix from thedelivering galley to the carrier and also from the carrier to receivinggalley.

The same letters designate like parts in the several views.

A is the carrier; B the measuring needle; 13 the mechanism for movingthe needle automatically to accurately position a matrix in the carrier;B the manually controlled mechanism coiiperating with the needle eitherto set the latter according to a standard matrix or to test a matrix; CC the milling cutters; D the pusher for transferring the matricesbetween the carrier and galleys E E; F the cradle for adjusting thecarrier relatively to the needle; Gthe microscope; H the handle fordisconnecting the pusher D from its operating mechanism; J J the handlesfor adjusting the cutters; K the electric control device for the needlemicrometer; M the main control handle; N the variable speed gear; and Pthe handle for effecting the stopping of the carrier in line with thegalleys.

The positioning and measuring needle B which is arranged horizontally(see Figs. 5, 5' and 6) is removably secured in a holder B which in turnis mounted in a bearing 5 in an arm of the machine frame X, The needleis moved forward to position the rough matrix in the carrier A throughthe mechanism B controlled conveniently by a. cam B hen moved forward,this needle projects through an anvil or gaging surface and engages amatrix Y which has al ready been placed in the carrier A before thelatter has been moved opposite to the needle 13.

From the position in line with the needle 13, the carrier A conveys thematrix between the two opposed rotating cutters C C (see Figs. 6 and 7).These cutters are mounted on shafts 0 a turning in suit-able bearings 0which latter are adjustable in the machine frame so that the cutters canbe adjusted relatively to one another and to the carriers, and eachcutter is provided with a separate drive, conveniently pulley and beltgear 0 The carrier A is automatically moved between the various stationsor positions. Preferably it is mounted upon a shaft (1 (see Figs. 7, 8,9 and about which it is turned by a cam 1 (Figs. 4 and 5).

The cam A transmits motion to the carrier A through a lever A mounted ona shaft A One end of the lever has a roller A bearing on the cam and toits other end is secured a spring A for maintaining the roller inconstant contact with the cam (see Fig. 12). To the shaft A is secured alever A (see Figs. 7 8, 9 and 10) which is connected by a link A to thecarrier A.

The carrier travels at a high rate of speed between the receivingposition and the gag ing position, from the latter to the cutters, andon its return from the cutters to the delivery position; but whenpassing the matrix between the cutters, its speed of travel is reduced,through the automatically coming into action of the variable speed gearN (see Figs. 1 and After the matrix has been acted upon by the cuttersthe carrier conveys it to the delivery position which is alsoconveniently the receiving position.

In the delivery position the finished matrix is ejected from theopposite side of the carrier to that by which it entered, by the pusherD (see Figs. A and 15) which is operated by a cam D (see Figs. 5 and 6)and after it has ejected a matrix the pusher is dawn back to allow arough matrix to fall or pass from the galley E in front of the pusher onthe next advance of which this matrix is pushed into the carrier.

The setting of the cutters or one of them is determined by a measurementarrived at by a preliminary contacting of the measuring needle B with astandard matrix, or depth gage. To obtain the necessary adjustment forthe cutter which is to operate on the matrix cavity end of the matrix, astandard matrix is placed against the anvil or gaging surface 0 throughwhich the point of the needle B will be projected. Conveniently thisstandard gage is placed in the carrier A and is held against or advancedagainst the anvil O by hand pressure applied to a spring controlledpusher 0 (see Fig. 5 The standard gage being in position, the slidingcam piece B of the mechanism B (see Figs. 5 and 6) by which the needleis moved automatically for positioning rough matrices in the carrier A,is withdrawn and the needle is advanced into con tact with the standardmatrix, conveniently by a spring 13. Mounted at the rear end of theneedle holder is the gaging mechanism B which comprises a rotatable camB carried upon a horizontal axis to which is also secured a hand lever Band a micrometer scale B arranged to be passed in front of a zero mark B(see Fig. 1). The bearings for the axis of the cam B are insulated fromthe casing. On the axis of .the cam is also carried a finely toothedsegment B (see Figs. 5 and 5 The mechanism 13 oooperates with theelectro-magnetic mechanism K (see Fig. 5 The lever B carries aninsulated stud K which passes through a slot 6 in the cam 13 and hasconnected at its free end one end of a spring K the other end of whichis attached to an insu lated plug K on the casing. At one end of theslot 6 is a piece of insulating material K againstwhich the pin isnormally pressed by the spring K which latter rests upon an insulatedsupport K. From the plug K a wire of the circuit passes to the magnet Kand thence to the battery, the other terminal of which is connected tothe carrier A. As thus arranged it will be observed that the electriccircuit including magnet K is normally broken or open between pin K andcam B When the lever B is turned downward (Fig. 1) it moves pin Kagainst the action of the spring K into contact with the opposite oruninsulated side of the slot 6 thus closing the circuit at this point,and thereafter rotates the cam B Adjacent to the cam is a pawl K heldout of contact with the teeth B by a spring, but arranged to engage andlock the cam when electromagnet K is energized.

The hand lever 13 rotates the cam 13 until the latter contacts with theend of the needle holder which, as stated, has been advanced by itsspring into contact with the standard matrix when the circuit will beclosed, energizing the magnet K which attracts the tail of the pawl K.The nose of the pawl then engages the toothed segment and thereby locksthe cam against further movement. The reading of the scale relatively tothe stationary zero mark B is then taken and should the zero on thescale not coincide with the stationary zero mark, then the cam must beset back from the needle holder, until the two zeros coincide. For thispurpose the shaft of the cam and the parts cooperating with the latterare all adjustably carried. Conveniently they are mounted in a casing orframe B hinged at B to the machine frame. This frame can be turned onits hinge B by a micrometer screw 13 which engages a lug on the casingThe lug is embraced by a strap B secured to the machine frame andcarrying a spring-controlled push piece B to hold the casing against theadjusting screw B This screw is adjusted for each standard matrix ordepth gage as much as is necessary to bring the stationary zero mark andthe zero on the cam scale into register, while the cam is in contactwith the needle holder. Then this reading is obtained, then the cuttersor that one acting on the character end of the matrix are or is setaccordingly.

Each cutter is provided with a setting device including a micrometerscrew. The cutter 0 has a setting handle J and the cutter c a similarhandle J (see Fig. 3 These ternally and pass through internally screwedsleeves. The bearings may be advanced or withdrawn to move the cuttersnearer to or farther away from each other (see Fig. 6).

The cutting mechanism having been adjusted to accord with the reading ofmicrometer screw B the latter is turned back to zero and a rough matrixis delivered to the carrier A and passed between the cutters, afterwhich it is again brought oppo site to the needle in contact with gage Oand the cam B once more advanced to test the adjustments. Should thematrix not prove to be of such dimensions that the zero of cam scale Bcoincides with the fixed zero mark, the departure from standard will beread on micrometer screw 13 and the cutter C will be readjusted so thatwhen another rough matrix passes between the cutters it will be milledto accurate dimensions. After the described measurements andadjustmentshave been effected pressure on lever B is withdrawn, cam 13 is retractedby its spring until it moves clear of the needle carrier, and micrometerscrew B is set to zero.

The cutters, once set to accurately mill a matrix of a particular sort,or with a particular character, will be accurately set for all matricesof that sort and need not be readjusted for that particular kind ofmatrix until either by wear of the cutters or the needle, a sutiicientinaccuracy arises to require resetting. This can always be discovered bytesting a milled matrix by the mechanism B The automatic movement of theneedle B to accurately position each matrix Y in the carrier A isobtained from the mechanism the extreme of the travel of said needle as1 1'1 determined by its engagement with stop B To the cam-piece isconnected by means of a stud one end of a lever B". (see Fig. 2) pivotedat Z) and having its other end connected to an arm B (see Fig. i)carried by a shaft B at the other end of which is a bellcrank lever B(see Fig. 11) one arm of which latter engages a cam B on the cam shaft Zand the other a cam 13 also on the same shaft.

Owing to the delicacy of the parts, the forward movement of the needleif positively performed is liable to result in damaging it or drivingthe point of it into the matrix which is usually of copper; therefore itispreferred to yieldingly advance the needle by the spring B and controland measure said advance by the cam piece against one inclined wall ofwhich block 13 is held by said spring. The forward movement of the campiece permits the advance of the needle under the action of the springwhile the backward movement of the cam piece compels retraction of theneedle.

A spring 13 acting on the bell crank lever B tends to keep this incontact with the cam B (see Figs. 11 and 12) and the needle advancingcam B is so shaped as to operate on lever B only when the positioningmovement is called for.

\Vhen the gaging mechanism B is to act upon the needle in the mannerhereinbefore described, it is necessary that the cam-piece B should bewithdrawn and for this purpose the lever B is provided with a handle B(see Fig. 2) which when pressed down withdraws the cam from engagementwith the block on the needle holder.

The matrix carrier at the beginning of the cycle is in position toreceive a matrix from the delivery galley E, which is also thedischarging position (see Fig. 7).

The matrices to be treated are stored in the galley E which is arrangedin a horizontally inclined position (see Figs. 2 and 7 to 10) thematrices being pressed toward the outlet or lower end by a weightedfollower 0 in a known manner. The outlet from the galley is normallyclosed by the pusher D which is mounted to move to and fro in suitablebearings in the cradle F which supports the delivery and receivinggalleys E E and the carrier A. lVhen the carrier is in this position thepusher D is advanced by the cam D on the shaft Z first to discharge afinished matrix from the carrier, and at the opposite side of the latterto that on which the matrices are delivered to the carrier. The pusheris then drawn back to uncover the outlet of the delivering galley E (seeFig. 15) and allow the leading matrix to fall into the path of thepusher which is again advanced and deposits the matrix in the carrier.The movements of the pusher are derived from the cam D convenientlythrough a lever D fulcrumed at (Z (see Fig. 12) and having one endengaging the cam while the other is connected to the pusher D by adetachable link D (see Figs. 1 and 5).

It is sometimes required that a matrix should not be discharged from thecarrier in every cycle of the machine, as for example when a matrix hasnot been brought to proper dimensions with one operation of the cutters,or when it is desired to test the accuracy of the machine, by themechanism B A matrix will remain in the carrier if and so long as thepusher D is disconnected or rendered inoperative. For this purpose thepivot (Z of the lever D is carried on a boss d fast on a shaft 61 (seeFigs. 11 and 12) and the latter is provided with a handle H by turningwhich from the position shown in full lines in Fig. 11 to that shown inbroken lines in the same figure, the end of the lever D is removed fromcontact with the cam D the joints between the lever D the pusher D andthe link D being of such a nature as to permit of this movement.

From the matrix receiving position (see Fig. 7) the carrier is moved toa position opposite the needle B (see Fig. 8) and on reaching thisposition, where a short halt or rest in the carriers movement takesplace, the needle 13 is advanced to accurately position the matrix inthe carrier by the mechanism already described, after which the carrierconveys the matrix between the cutters C C (see Figs. 9 and 10) where itis milled and finally the carrier moves back to the delivery position.

The matrix is delivered from the carrier by the pusher D as stated, andis deposited in a channel at the entrance to the receiving galley E intowhich it is moved laterally by a pusher D, the latter engaged by a leverl) advanced by a cam D (see Figs. ll and 15) and returned by a springD".

The carrier is provided with a seat A for the matrix, said seat beingformed between fixed and movable jaws each provided with an angulargroove for receiving opposite corners of the matrix, the receiving endsof said grooves being slightly beveled to facilitate the entrance of thematrix when projected from the delivery galley. The movable jaw A of thematrix seat slides in a guide a on the carrier and is provided with apin a (Fig. 10) which abuts against the rear end ofsaid guide to limitthe forward movement of said aw. Movable in guides in the carrier inrear of jaw A is a head a to which is secured a headed pin a, the latterpassing through a sliding head A carrying a roller A engaging a cam Athe latter turning on shaft a. Between jaw A and head a is interposed aspring A and between heads a and A is interposed another and strongerspring A. Spring A serves to project aw A and contract the seat A sothat when a matrix is inserted from the end thereof said jaw A will beforced back and caused to grasp the inserted matrix with a lightpressure, sullicient in degree to retain the matrix and at the same timepermit longitudinal displacement thereof by the needle when brought intocontact therewith. Spring A forms a yielding connection between the jawand its actuating cam. The cam A is turned in one direction, to advancethe jaw, by a link A connected to a lever A which is secured to a sleeveA carried loosely on the shaft A. and to this sleeve is fixed an arm Awhich engages a cum A on the cam shaft Z. -When the cam is turned in theopposite direction the jaws open.

The speed of travel of the carrier is reduced as stated, when thecutters are in action, by the variable speed gear N which isautomatically brought into operation and which is preferably of theepicyclic type.

During the major portion of the cycle of operations, this gear is idleas a speed-reducing gear. It is mounted on a shaft N to which motion iscommunicated by double belt and pulley gear N N The gear N when highspeed drive is in use acts to lock the driving pulleys to the shaft N.Motion is taken from the shaft N and communicated to the cam shaft Z bya pinion N* on the shaft N gearing with the idle pinion N which alsogears with a pinion Z carried by one member of a clutch on the cam shaftZ.

Connected to the pulley N which is loose on the shaft N is a pinion N ofthe gear N. This pinion gears with members N of double pinions carriedon a disk N and the other members of the double pinions N 7 gear with apinion N fast on the shaft N. Pulley N is mounted to rotate on a sleeveattached to disk N and is connected to the latter through a frictionclutch N When the carrier approaches or reaches the cutters, aprojection N on the cam shaft, or, as in the present embodiment, mountedupon the cam D engages a trigger piece N (see Fig. 13) carried on apivoted pawl or stop N and by turning the latter on its pivot 07,against the action of a controlling spring N causes the pawl to engageone or other tooth of a ratchet N on the disk 1 9 of the variable speedgear N. For high speed, the members of the gear interlock and the entiregear revolves bodily as one piece, the speed of the driving members orpulleys N N being transmitted to the pinion 1 4 and thence to the camshaft. lVhen, however, the pawl N engages and arrests disk N the counteracting influence of pulley b is suspended and the drive of the pulley Nis transmitted through theepicyclic gear to the pinion N at a reducedspeed. During the reduced speed the pulley N is idle and slips.

Conveniently the pawl N is connected toits support through a dashpotdevice 1 for absorbing shock and the trigger N is also resilientlysupported by a spring N (see Figs. 10, 11 and 13.)

The needle B, either when positioning a matrix or measuring the depth ofthe drive therein, must, make contact with part of the face of thecharacter, and as each character is different from another in formation,the carrier A should be adjustable in two directions relatively to theneedle 13 while maintaining the face or end of the matrix body Y inconstant relation with the anvil O. For this purpose the shaft a of thecarrier is rotatably mounted in the cradle F which carries the galleys EE and is mounted so as to be capable of turning on or with a shaft 7(see Figs. 7 to 10). The movements of adjustment of the cradle F andcarrier A are controlled by two cams F F mounted co-axially, the cam Fbeing controlled by a handle F and the cam F by a handle F The cam Facts upon one end of a pivoted lever F 5 the other end of which bearsupon a sliding bolt F which acts upon a horizontally arranged bar F Theends of the bar F are carried in arms F pivotally supported on thecarrier shaft a. The lever F and the bar F are connected together by aspring F The carrier A when in position in line with the needle B bearsagainst the bar F (see Fig. 8) so that the position of the matrixhorizontally can be adjusted and determined by the movements of the barby the cam F. The cam F 2 acts upon a stud F in a downwardly extendingmember of the cradle F (see Fig. 7) and when operated causes the carrierto turn around the shaft f, thus adjusting the carrier and therefore thematrix therein vertically relatively to the needle. The adjustments arecarried out under the direct observation of the operator through themicroscope G, the character being reflected by the mirror 9 thereof (seeFig. 5*). On account of these adjustments and as the carrier must cometo rest at the receiving and delivering position so that the seat thereregisters with the galley openings and with the pusher D, mechanism isprovided to insure this in all cases. A stop Q, (see Figs. 5, 5*, 7 8and 9) is operated from a cam Q which acts 011 a sliding piece Q mountedin the machine frame and bearing a ainst one end of a lever Q aivoted atQ the other end of which embraces the stop Q. This stop is normally heldout of the path of the carrier by the cam but when released is advancedinto said path by a spring Q acting upon a bolt Q which bears on thestop Q (see Figs. 5 and 5 In order that the carrier driving mecha nismmay not be interfered with by the adjustments of the carrier as abovereferred to a spring coupling or spring-box A* is introducedconveniently between two parts of the link A (see Fig. 10).

The cam shaft Z is in two parts placed end to end and coupled by aclutch Z (see Figs. 4, 5, 12 and 13.) The clutch is normally held closedby a contractile band Z between the meeting end of which is mounted arocking piece Ztwhich when obstructed during the revolution of theclutch is rocked and forces the ends of the band Z apart thus openingthe clutch.

The main starting handle M is connected to a pawl or stop M which isnormally forced into the path of the rocking piece Z by aspring-controlled bolt M On the depression of the lever M the pawl isWithdrawn against the power of the spring, and the clutch closes totransmit the drive and will remain closed until the passage of the pieceZ is again obstructed.

When the clutch Z is opened by the oper ation of the lever M the carrierwill be arrested in the position Opposite the needle B, so that theaccuracy of a matrix can be tested. Another handle P is provided and isconnected to a pawl or stop P (see Figs. 13 and 15). By turning thehandle P the stop P will be projected into the path of the rocking pieceZ and effect the opening of the clutch at the required point to stop thecarrier at the galleys.

T 0 enable the parts to be moved readily by hand, a hand wheel R ismounted on a shaft R which carries a pinion R gearing with the pinion Z.

By releasing the strap or catch B from the casing B this latter can beturned down on its hinge to allow the needle and needle holder to bewithdrawn.

Access can be had to the cutters by disconnecting the link D and a catchsecuring the galleys E E in position. These can then be turned on axisout of the way.

The cutters can be released by unscrewing the rods 0 C by which they areretaine'd; the rod C is accessible from the outside of the machine, butthe rod (1 being inaccessible from the outside is provided with asliding and rotatable spanner C (see Fig. 6).
